IKS: IGNITION BATTERY: All DLA Engine Ignitions operate within a 6.6 V DC to 8.4 V DC range. A-123-Series, LiPo are commonly used. However, good quality Nickel-Metal-Hydride (NiMH) battery, in a six- (6) series configuration, is also adequate. An 1,200 mAh battery is sufficient. However, a 2,100 mAh battery is recommended for the Dual Ignition engines.
The DLA Engine has been specifically designed, developed and manufactured from proprietary components for larger (32cc and up) size Model Aircraft. The DLA series of engines are very powerful, exceptionally light weight for its class, easy to operate and adjust. DLA engines should provide years of satisfactory performance, if maintained properly.

ENGINE INSTALLATION IN MODEL AIRCRAFT Mount Engine to Model Aircraft Firewall: Prior to mounting or re-mounting any DLA engine onto the aircraft, review all safety instructions, check to be sure all engine bolts, plugs, etc. are securely in place. Check the engine thoroughly for any damage, cracks, or unusual wear.

9. The supplied stand-offs set the minimum distance between engine’s carburetor and the firewall. If you use non-DLA Stand-offs, do not decrease this distance. If you cannot maintain this minimum distance, you may want to consider cutting a hole in the firewall, directly in line with the carburetor with a diameter approximately equal the diameter of the carburetor’s intake.
MUFFLER INSTALLATION: Attach the DLA muffler to the engine using the two (2) supplied, 5.0 mm x 0.8 mm – 16mm Socket Head bolts and gasket supplied. No gasket sealant is required. The DLA 64 & 116cc engine has two (2) mufflers and therefore, four (4) each attachment bolts and two (2) gaskets.
